Description

Pedro Robot is an Open Source Robotic Arm 4 axes designed in France and fully 3D printed. This robot is easy to program with an Arduino Software (IDE), it can catch and move some objects with a high precision. Pedro Robot is fun and safe way to learn for teacher, student, programmer, artist, designer, amateur or even curious to learn the basics of robotics.

Details

Pedro Robot full kit is available on Tindie:

You can also order your Pedro Robot 3D printed on Thingiverse:

Pedro Robot - Demonstration

See below for the Arduino code used for this demonstration.

Hardware

Pedro Robot is equipped with 4 mini SG90 servo motors.

The servo motor 1 placed at the base of Pedro Robot allows it to rotate 180 degrees on itself giving a very wide field of view of its environment.

Servo 4 is Pedro Robot's gripper which allows it to catch any object in its field of view and move.

Pedro Robot is a programmable robot with the Arduino IDE thanks to an embedded card equipped with an Atmega328 microcontroller with a storage capacity of 1024 bytes enabling it to record a sequence of 255 positions on each axis and to replay them continuously. The Pedro board is powered by 5V 4A and has 2 pushbuttons each connected to a pilot led allowing different functions to be realized (example: button 1 to register or initialize the movements of the robot, button 2 to replay or stop robot movements, "You're only limited by your imagination" Pedro Robot can be controlled by 4 potentiometers, each connected to an axis, base, shoulder, elbow and gripper. The Pedro card has a USB TTL serial link to connect Pedro Robot with a computer.

Despite the simplicity, this is a really great design. I love how compact it is. Would be a great learning tool for kids. Plus I reckon you can make this extremely cheap and produce them very fast. I would be tempted to print loads and get them all going at the same time!!

Hi @Dan DWRobotics. You are right, the design of Pedro is very simple and can be a great learning tool for children or students to understand the basics of robotics. A copy of the robot with complete kit and 3D accesory is already available on tindie.com for only $61. The programmable board with Atmage328, USB cable and serial link USB TTL is also available for only $19. You can already print Pedro Petit Robot for free with .stl files available at thingiverse.com. Enjoy it.
